The economy of the Amazon region relies heavily on water for transport and livelihoods. Important also for the regional water cycle, the Amazon ecosystems are threatened by climate change, although there is little knowledge about the likelihood of adverse events and potentially related vulnerabilities.

The River Nile provides an invaluable source of livelihoods to over 160 million of people who dwell in its valley. The river valley is renowned for being a cradle of civilisation. As the populations grew and civilisation evolved, the demand for more water resources took a toll in the region. The more recent visible climate change effects have further compounded water management in the basin.

Water and soils are increasingly becoming a limiting resource for meeting the food requirements
of a growing world population. Integrated concepts for managing natural resources in a sustainable
and environmentally sound manner show encouraging impacts, if applied on a large scale and
over a long period like in Tigray, the northernmost regional state of Ethiopia.

Poverty in rural households have deepened in the past two years through world events: unprecedented rises in food and fuel prices were followed by global economic meltdown, all amidst growing climate uncertainty. Balancing water availability within and across growing seasons, water harvesting helps to buffer households against drought.

Water is scarce in India's semiarid zones of Rajasthan. Climate change is putting additional pressure on the rare resources. Irregular or no rainfall forces many small farmers to abandon their fields, at least temporarily, and seek work in the towns.

Many adaptation measures urgently needed in agriculture today as a consequence of climate change concern water in agriculture and were already devised and implemented in the 1980s as a part of rural development activities. However, most of the experience and knowledge have sunk without trace.

The world food crisis has spurred foreign direct investments (FDI) into arable land in developing countries. While significant financial inflows into agricultural sectors could be beneficial on a global scale, it could negatively affect local livelihoods. This article provides an overview of the different types of FDI in land.

In Germany, the debate about the security/development nexus is gathering pace. The reality of life in crisis regions, the management of post-conflict situations and the precautionary anticipation of demands arising in the context of crisis management all require the highest level of coordination at political and local level and on a cross-sectoral basis.

A team of German and Spanish scientists has genetically modified a maize plant in a way that markedly increases the level of three vitamins in the maize kernels. The level of betacarotene, the precursor to vitamin A, was raised by a factor of 169, the level of vitamin C increased six-fold and the level of folic acid, a vitamin of the B group, doubled.

A importância das florestas para a conservação do planeta e para o bem estar das gerações futuras é cada vez mais reconhecida pela enormidade de bens e serviços prestados à humanidade: elas contribuem para o equilíbrio do clima e das águas, abrigam uma valiosa biodiversidade, além de representar alternativa socioeconômica às populações que nelas vivem e de suprir a demanda da soc

Au Mali, au début des années 1990, la décentralisation fut d’abord un acte politique permettant de proposer une solution viable au problème de la rébellion touarègue.Ensuite, les aspirations aux idées occidentales démocratiques (pluralisme politique,liberté de la presse, etc.) d’une partie des élites urbaines ont rencontré les plans des occidentaux pour le développement de l’Afrique pour donner

The aim of this study was developing a scale with which to measure farmers’ attitude towards complete ownership of farmland. The research started by identifying 50 different statements based on review of the empirical literature and information obtained from stakeholders and experts.
